15 Claims.

This invention relates to air outlet devices for ventilating apparatus, and has particular reference to improvements in air outlet devices for controlling the delivery of fresh or treated air from air supply ducts into rooms or other enclosures.

- Generally speaking, the object of the invention is to provide a simple; inexpensive air outlet device embodying a novel combination and arrangement of air-flow control elements; and pro.- vision for adjustments of certain of the same relative to another or others thereof, whereby the delivery of air through the device may be regulated with exactitude as to amount between a maximum and total denial, and the delivered air may be caused to flow from the device in various different directions and manners for particular purposes in particular instances.

'With the foregoing general object in view, the invention consists in an air outlet device embodying the novel features of construction, combination and arrangement of parts as 'willbe hereinafter more fully described, illustrated in the accompanying drawing and defined in the appended claims.

In the accompanying drawing, wherein like characters of reference denote corresponding parts in the different views:

Figure l is a central, vertical section through an air outlet device constructed in accordance with one practical embodiment of the invention.

Figure 2 is a top plan view of the device shown in Fig. l; and

Figures 3 and 4 are fragmentary diagrammatic views similar to Fig. 1 illustrating variousalternative constructions of the device.

Referring to the drawing in detail, first with particular reference to the specific embodiment of the invention illustrated in Figs. 1 and 2, it will be observed that the present air outlet device comprises a neck Ill for connection with an air supply duct to have air delivered therethrough from said duct; a series of axially spaced apart ring-like air deflecting members ll disposed in advance of the lower or air outlet end of said neck in axial alinement therewith, and an air intercepting and deflecting disk unit l2 axially alined with said neck and said members and mounted for axial adjustment between a position closing said neck against the escape of any air therefrom andvarious different positions in advance of said neck and with respect to said members to regulate the amount of air delivered from said neck and. its direction of flow therefrom.

It will further' be-observed that the neck I8,

the openings in the members H and the disk unit 12 are circular in shape;-that the opening" in the uppermost of said members H is of approximately the same diameter as the neck '10 and is fastened to said neck at the lower or ou tlet end thereof that thjope'ning in the lowermost of said members I'l also is of approximately the same diameter assaid 'neck; that stays l3con nect said members H together; that the disk unit I! is of approximatelythe same diameter as the neokglo' and'the opening in the lower-' most member I l;-that the openings in intermediate members H, of which there may be" any desired numbe -are, progressively upwardly, of progressively -increasing diameters greater than the diameter of saidneck, and thatsaid members .II are, progressively upwardly, ofprogressively increasing external diameters.

The disk unit-l2 maybe-mounted for axial adjustment inany suitable jmanner, but one simple and practical means for this purpose may comprise, as shown, a threaded-rod Msuitably fastened thereto, centrally thereof, and extending upwardly therefrom; and a nut I 5 which may be mounted in any suitable manner within the neck [0 axially thereof and into'which said rod is threaded. Thus, by rotating said rod, said disk obviously'may be axially adjusted to an upper position closing the loweror outlet end of the neck It] against the escape of any air there from; to a lower position in advance of or below the lowermost member H, and to any one of an infinite number of positions with respect to the members ll between its said upper andlower positions. I v

The disk unit I2 may comprise simply a single disk elementtotallyclosed against the flow ofany air therethrough; or it may comprise, as shown, a pair of superimposed disk elements It and I! which are suitably apertured as indicated at l8 and 19, respectively, and one of which is-suitably mounted for rotation relative tothe other to aline and disaline the openings 18 and I9. Thus, even if said disk unitlcomprises two disks as shown, it is, in effect, andto all intents and purposes, the same as a single disk when the openings l8, is are closed. On the other hand, by rotating one of the disk elements'relative to the other to aline the openings l8, l9 to a greater or lesser extent, greater or lesser amounts of airmay be permitted to flow directly downwardly through said disk unitm, y

Assuming that the openings l8, l9 are closedand that'the disk unit l2 therefore'isthe equivalent of a single, closed disk, it is manifest that the same, in any position of adjustment thereof in advance of or below the lower or outlet end of the neck ID, will intercept air flowing downwardly from said neck and deflect it laterally outward. It is further manifest that, depending upon the position of adjustment of said disk unit in advance of the neck l and relative to the members H, and upon the internal and external diameters of said members, not only the amount of air delivered from said neck, but also its direction of flow from the device, may be regulated Assuming, for example, that the disk unit 12 is adjusted to a postion in the plane of the lowermost member I I, it is apparent that most of the supplied air will be deflected laterally outwardly and very little of it will flow downwardly. If, on the other hand, the disk unit is adjusted to a position below the lowermost member 'I I, as shown, a lesser amount of the air will be deflected laterally outwardly by said disk unit and said members H and agreater amount will be permitted to flow more or less downwardly between the inner edge of any one member II and the outer edge of the next adjacent lower member i i.

Obviously, both the internal and theexternal diameters of the members I I may be varied within wide limits to insurecertain more or less definite directions of flow of the air for different positions of axial adjustment of the disk unit l2, the possibilities in this connection being infinite. In fact, it is possible in this connection to provide members H of such diameters, and to adjust the disk unit I2 to certain positions with respect to them, suchithat it will direct the delivered air to produce more or less of an aspiratory action or inflow of air through one or more of the spaces between the members H, thus to insure intermiXture of the supplied air with the room or other enclosure air within the device and in the immediate vicinity exteriorly thereof.

Obviously, in any position of axial adjustment of the disk unit l2, the openings 18, l9of said disk unit may be more or less alined' to permit more'or less of the supplied air to be delivered directly downwardly through said disk unit.

A device constructed in accordance with the invention may comprise only a single member H instead of a series of any desired number of such members. Moreover, regardless of the number of the members I l comprised in any given device, the internal and the external diameters of said memher, or members, as thecase may be, may be of any desired dimensions. Likewise, the disk unit 12 may be of any desired diameter either the same as, or greater or lesser than, the diameter ofthe neck [0. Thus, referring particularly to Fig. 3 of the drawing, it will be observed that the device includes only a'single ring-like member, designated as II; that the internal diameter of this member is greater than thediameter' of the neck, designated as I0 and that the disk unit, designated as I2 likewise is of greater diameter than said neck i0 and of approximately the same diameter as the internal diameter of the member II. On the other hand, it will be observed by particular reference to Fig. 4 that the internal diameter of the single ring-like member, designated as li is lesser than the diameter of the neck, designated as I0 and that the disk unit, designated as I2 also is of lesser diameter than said neck and of approximately the same diameter as the internal diameter of the member li In each of the figures of the drawing the ringcontrolled within wide limits.

therein, fdesired shape but preferably is of the same shape like air flow control members have been illustrated, as being flat. Manifestly, however, any or all of these members in any given device may be of flaring form as shown, for example, in Kurth Patent No. 2,185,919, of January 2, 1940. Moreover, instead of said members being of circular shape and having openings of circular shape therein, they may be of rectangular, hexagonal, octagonal or any other desired shape and, regardless of their shape, may have either circular openings or openings of any other desired shape Likewise; the disk unitmay be of any as the openings in the air flow control members,

- and if said unit is of other than circular shape it may be mounted in any suitable manner other than as shown for adjustment relative to said air flow control members.

From the foregoing description considered in connection with the accompanying drawing it is believed that the construction, operation and advantages of the invention will be clearly understood. It'is desired to point'out, however, that while only certain specific structural forms of the invention have been illustrated and described, the same is readily capable of embodiment in a variety of specifically difierent structural forms within itsspirit and scope as defined in the appended claims.
